A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?

Choice A rationale:

The nurse should instruct the client to sleep with an extra pillow under their head. This position, known as the semi-Fowler's position, elevates the upper body and head, which can help reduce shortness of breath and difficulty breathing while lying down at night. Propranolol, a non-selective beta-blocker, can cause bronchoconstriction in some individuals, especially those with a history of respiratory issues. Elevating the head can assist in improving lung expansion and reducing the sensation of breathlessness.

Choice B rationale:

Sleeping on their left side would not be the best option in this case. While sleeping on the left side is often recommended for individuals with certain cardiac conditions to improve blood flow and reduce pressure on the heart, it may not be as effective for alleviating the respiratory symptoms caused by propranolol. Elevating the head is a more appropriate intervention in this scenario.

Choice C rationale:

Sleeping on their right side is not the ideal choice either. While it can have benefits for individuals with certain cardiac conditions, it does not address the specific respiratory symptoms reported by the client. Elevating the head is a more targeted intervention to alleviate breathlessness associated with propranolol.

Choice D rationale:

Sleeping on their back may worsen the client's symptoms. Lying flat on the back can lead to increased pressure on the diaphragm, making it more challenging to breathe for individuals experiencing shortness of breath. Therefore, it is not the recommended position for this client.

Choice A rationale:

Tetracycline antibiotics can form insoluble complexes with calcium, reducing their absorption when taken together. Therefore, advising the client to continue taking calcium supplements with food while on tetracycline therapy is not recommended as it may decrease the effectiveness of the antibiotic.

Choice B rationale:

The nurse should advise the client to avoid taking calcium supplements while on tetracycline therapy. Calcium-containing products (such as supplements, dairy products, and antacids) should be taken at least 2 hours before or after tetracycline administration to minimize the interference with drug absorption.

Choice C rationale:

Taking calcium supplements with tetracycline, even with plenty of water, can still lead to reduced drug absorption due to the formation of insoluble complexes. Therefore, this advice is not appropriate.

Choice D rationale:

The nurse should recommend that the client take calcium supplements at least 2 hours before or after tetracycline. This approach ensures that the client receives the full therapeutic benefit of the antibiotic while still meeting their calcium needs separately.
